Title: Electric field emitting type display device
Inventor: SUDA JUNKO
IPC: C09K11/08
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To reduce discharge amount of gas and moisture from a phosphor during conduction and to reduce emission degradation of an FED(field emission display), by setting contents of elements other than phosphor compositions in the phosphor constituting a phosphor layer to be lower than a specific value. SOLUTION: Because a flux adhered to a phosphor intends to store moisture, each of RGB phosphors is produced in a manufacturing method using the flux, this is sufficiently cleaned with nitric acid or acetic acid to remove impurity containing the flux as much as possible, and the impurity other than phosphor compositions is lower than 10 ppm. An FED produced like this is smaller in brightness degradation and long in life. In other method, aqueous solution of nitrate of phosphor material is produced, and urea is added to perform coprecipitation with hydroxide and is baked and synthesized into phosphors of oxide. In this case, flux is not used, each of RGB phosphors is separately synthesized. Gas, especially moisture stored in the phosphors themselves is reduced to improve a life characteristic.

Inventor: HAYASHI TETSUYA
IPC: H01L29/80
Filed: 1998-02-03
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device having high current amplitude, while the breakdown voltage is maintained. SOLUTION: A first groove having a fixed-potential insulating electrode 6 in the inside and a second groove which is not in contact with a source region 3 are provided. In the inside of the second groove, a variable-potential insulating electrode 16 comprising a MOS-type electrode 14 and a second insulating film 15 is provided. Furthermore, the second groove is arranged in the vicinity of the end of the first groove. In contact with the second insulating film 15, a gate electrode 8 is provided, which is not in contact with the source region 3. The second MOS-type electrode 14 is connected to the gate region 8 in this constitution.  In shielded state, since the second groove is located in the vicinity of the end part of the first groove, the electric field is concentrated at the first groove end, even if the drain potential rises up, and avalanche breakdown condition will not be reached. In a conducting state, although a part of many carriers flowed out of the source region 3 becomes a part of a gate current, if the gate region 8 is shallow and small, the rate of the multiple carriers dissipating in the gate region 8 is low, and the value of the gate current required for flowing a constant main current can be suppressed low.
